Mission San Francisco Solano de Sonoma was founded in 1823 by Father Junipero Serra. Sonoma was first formed in 1835. It was incorporated as a city in 1881 (2nd time). The famous plaza was constructed under the leadership of Mariano Guadalupe Vallejo. The 8 acre plaza is still the largest in the state. For a time, Vallejo was the military governor of the state in 1838.

Sonoma was the site of the Bear Flag Revolt which established California as a Republic on June 14, 1846. Sonoma was proclaimed the capital of California for 25 days during this time. This ended when California was annexed by the United States.

In 1854, Santa Rosa became the county seat over Sonoma though at the time, there were many questions as to the validity of the election.
